          最近四五年间，互联网行业似乎总是绕不开社交网络这个概念。无论是旗舰级别的传说中的facebook、LinkedIn，还是如雨后春笋般冒出来的各种团购和微博网站，全都或多或少地体现着SNS（社会网络服务）的特色。这些五花八门的产品，在丰富我们业余生活的同时，也为研究者提供了大量珍贵的数据。以往只能依靠有限的调研或模拟才能进行的社会网络分析（SNA），现在具备了大规模开展和实施的条件。国内著名而典型的SNS网站“人人网”，最近依靠上市新闻重新赢得了大家的关注。本文基于人人网的好友关系数据，应用统计分析软件R做了社会网络分析的一些尝试。
         </p>
         <p>
          注：网络边界的确定，是社会网络分析的关键而困难的步骤。由于数据获取的限制，本文分析的对象限制于作者的好友。也就是说，本文分析的网络是作者自己的好友圈子，读者看了这些分析结果或许会觉得索然无味，感兴趣的同学可以分析一下自己的社交网络，看看是否会有类似的结果。
         </p>
         <p>
          2013-03-23 做了相应的R包，分别用于
          <a href="https://github.com/yibochen/weiBor" target="_blank" title="github.com/yibochen/weiBor">
           新浪微博
          </a>
          和
          <a href="https://github.com/yibochen/Renren" target="_blank" title="github.com/yibochen/Renren">
           校内网
          </a>
          ，本文的脚本不再做更新。
         </p>
         <h2>
          一、读取数据
         </h2>
         <p>
          之所以选择人人网作为分析的对象，很重要的一点原因在于其数据获取较为便利。本文读取数据的过程借助了一款命令行浏览器cURL，这个浏览器在R中可以用RCurl包实现，简要的中文介绍建议参考
          <a href="http://cos.name/cn/topic/17816" target="_blank">
           medo的《R不务正业之RCurl》
          </a>
          。通过RCurl的简单编程，我们可以在R中实现登录人人网、发布状态以及读取页面数据等功能。
         </p>
         <p>
          人人网好友列表页面的url为
          <code>
           http://friend.renren.com/GetFriendList.do?curpage=0&amp;id=****
          </code>
          ，其中curpage为页码参数，id为相应的用户。通过对id与curpage做简单的循环，作者读取了自己（陈逸波）的所有好友以及好友的好友。（读取数据的R代码见文末附件。）
         </p>
         <p>
          用上述代码读取到的数据集记为friend_all，该数据有如下的格式：
         </p>
         <pre class="brush: r">set.seed(13)
friend_all[sample(1:nrow(friend_all), 10), ]</pre>
         <pre>                u0        id0     u1       id1
68282          沈叶  229657865 邢凤婷 238382560

         <p>
          其中，第一行数据表示“沈叶”与“邢凤婷”是好友关系，id0与id1为相应的用户id。需要注意的是人人网中不可避免地会出现同名用户的情况，因此id才是用户的唯一标识。
         </p>
         <h2>
          二、绘制简单的好友关系网络图
         </h2>
         <p>
          本文分析的焦点集中于作者的好友之间形成的网络，因此考虑做网络图来直观地展示网络的结构。
         </p>
         <p>
          首先，从上述读取到的数据集中筛选出希望分析的子集。这个子集包含了两个条件：
         </p>
         <p>
          （1）网络中没有作者自己（否则会呈现以作者为中心的分布，失去了分析的意义）；
          <br/>
          （2）网络中的用户都是作者自己的好友。
         </p>
         <pre class="brush: r">uid = "41021031"
## "41021031"是用户的uid，在读取数据的代码中可以自动获取
friend_all[, 2] = as.character(friend_all[, 2])
friend_all[, 4] = as.character(friend_all[, 4])
tmp1 = friend_all[friend_all[, 2] == uid, ]
tmp2 = friend_all[(friend_all[, 2] != uid) &amp;
                  (friend_all[, 4] %in% tmp1[, 4]), c(2, 4)]
## tmp1 = tmp1[tmp1[, 4] %in% c(tmp2[, 1], tmp2[, 2]), ]
## 这句话本意是用来去掉那些孤立点。在后面用degree的方式做掉了。</pre>
         <p>
          然后就是直接利用igraph包的做图功能绘制相应的网络图。考虑前面提到的用户同名情况，直接用id来做后续的分析。
         </p>
         <pre class="brush: r">library(igraph)
people = data.frame(id = tmp1[, 4], name = tmp1[, 3])
gg = graph.data.frame(d = tmp2, directed = F, vertices = people)
is.simple(gg)

          从图中可以直观地看出，作者的好友网络存在一定的人群分割，可以尝试对这个网络进行一些分析以提取出其中相对独立的子群（或者称为社群）。
         </p>

          三、子群分割
         </h2>
         <p>
          信息的分类和过滤是社会网络服务的一项特征，例如人人网对好友关系有一套自己的分类方式，用户可以自行对好友进行分组，从而对信息的收发做分组的管理。但是作为用户却未必能够养成并保持这种分组的习惯（例如作者自己就从来没有对好友做过分组）。与此同时我们揣测，作为真实关系的线上反映，人人网的好友网络是能够自动呈现出一定的人群分割的，而在社会网络分析中，对网络成分的分析也确实是一项重点。通过分析网络的结构，提取出其中的子群，能够让我们更好地理解这个网络的组成方式，从而更好地管理和利用信息流。
         </p>
         <p>
          寻找子群的算法有很多，igraph包提供了若干函数以实现对网络子群的搜索，本文采用了其中的walktrap.community()函数，更多细节及其他算法可以查看帮助文档。
         </p>
         <p>
          为了在网络图中展示这些子群，我们采用不同的颜色来标记他们。
         </p>
         <pre class="brush: r">com = walktrap.community(gg, steps = 5)
subgroup = split(com$labels, com$membership)
## subgroup
V(gg)$sg = com$membership + 1
V(gg)$color = rainbow(max(V(gg)$sg))[V(gg)$sg]
## png("net_walktrap.png", width = 500, height = 500)
par(mar = c(0, 0, 0, 0))
set.seed(14)
plot(gg, layout = layout.fruchterman.reingold, vertex.size = 5,
    vertex.color = V(gg)$color, vertex.label = NA, edge.color = grey(0.5),
    edge.arrow.mode = "-")
## dev.off()</pre>

          </a>
         </p>
         <p>
          从图中可以直观地看出好友网络已经被划分为若干相对独立的子群。这也与我们对人人网（尤其是其前身校内网）的直观理解相符合——人人网的好友关系基本都是真实线下关系的反映，很自然地可以划分为初中同学、高中同学、大学同学，等等（例如网络的上半部分为小学及中学的同学，下半部分为大学同学，而左侧的五个节点，那是统计之都的同学们。）。
         </p>
         <p>
          具体地看一下划分得到的子群，就能够更好地理解子群的含义。作者挑出了比较典型的几个子群，其中包括：
         </p>
         <p>
          “实验室同学”（子群9）
         </p>
         <pre class="brush: r">subgroup[[9]]</pre>
         <pre>[1] "周莉"      "杨志昌"    "潘伟"      "卢进文"   "胡刚"</pre>
         <p>
          “校内论坛上某版版友”（子群7）
         </p>
         <pre class="brush: r">subgroup[[7]]</pre>
         <pre> [1] "曲文君"       "翟传鑫"       "梁玮"         "单广宇"
 [5] "花木马leeear" "王昉"         "李典"         "陈侃"
 [9] "王祎萍"       "牛智"         "郗旺"         "何志嵩"</pre>
         <p>
          “高中学弟学妹”（子群11）
         </p>
         <pre class="brush: r">subgroup[[11]]</pre>
         <pre> [1] "邹舒怡"      "封启云"      "何非"        "朱亚希"      "陈平"
 [6] "洪怡君"      "程功"        "李常然"      "朱燕＾＾Jue" "周飏 Ivy"</pre>
         <p>
          “统计之都”（子群8）
         </p>
         <pre class="brush: r">subgroup[[8]]</pre>
         <pre>[1] "魏太云"   "邓一硕"   "吴云崇"   "高涛"     "统计之都"</pre>
         <p>
          其他子群还包括“大学同学（数学系）”、“大学同学（非数学系）”等等，不一而足（甚至能够区分高中的不同班级的同学）。因此可以认为上述算法得到的子群划分是合理且有意义的。
         </p>
         <p>
          更进一步地，可以对照网络图来考察各个子群成员的分布情况。例如大学数学系同学（下方蓝色点）的链接较为紧密，而非数学系的大学同学（主要是校内论坛CC98上的朋友，下方红色点）的分布则相对分散。通过网络密度可以定量地印证这一点：
         </p>
         <pre class="brush: r">## 数学系
sg10=subgraph(gg,V(gg)[sg==10])
## 非数学系
sg1=subgraph(gg,V(gg)[sg==1])
graph.density(gg)
## [1] 0.06376068
graph.density(sg10)
## [1] 0.5883441
graph.density(sg1)
## [1] 0.1223607</pre>
         <h2>
          四、起到中介作用的那些好友
         </h2>
         <p>
          在社会网络分析中，对节点的中介作用有一个经典的刻画叫做“中间度”。中间度衡量了节点作为中介的程度，当网络中某个个体的中间度较大时，我们认为它在很大程度上起到了中介和沟通的作用。常用的中间度的定义是$\sum(g_{ivj} / g_{ij}, i \neq j,i \neq v, j \neq v)$，其中$g_{ij}$表示联通i与j两个节点的捷径的条数，$g_{ivj}$则表示联通i与j两个节点且经过v的捷径的条数（所谓捷径，就是两个节点之间的最短路径）。在igraph包中，
          <code>
           betweenness()
          </code>
          函数能够简单地计算网络中各个节点的中间度。
         </p>
         <pre class="brush: r">V(gg)$bte = betweenness(gg, directed = F)
## png("net_betweenness.png", width = 500, height = 500)
par(mar = c(0, 2, 0, 0))
plot(V(gg)$bte)
## dev.off()</pre>
         <pre><a href="http://cos.name/?attachment_id=" rel="attachment wp-att-3339"><img src="http://cos.name/wp-content/uploads/2011/04/betweenness1.png"/></a></pre>
         <p>
          根据得到的中间度散点图，我们人为地选择了3000作为分界点，选取中间度高于3000的节点并在图形中利用节点的大小展示出来。
         </p>
         <pre class="brush: r">V(gg)$size = 5
V(gg)[bte&gt;=3000]$size = 15
## 当然啦这里的3000换成分位数之类的会更合理
V(gg)$label=NA
V(gg)[bte&gt;=3000]$label=V(gg)[bte&gt;=3000]$name
V(gg)$cex=1
V(gg)[bte&gt;=3000]$cex=2
## png("net_walktrap_betweenness.png", width = 500, height = 500)
par(mar = c(0, 0, 0, 0))
set.seed(14)
plot(gg, layout = layout.fruchterman.reingold, vertex.size = V(gg)$size,
    vertex.color = V(gg)$color, vertex.label = V(gg)$label,
    vertex.label.cex=V(gg)$cex, edge.color = grey(0.5),
    edge.arrow.mode = "-")
## dev.off()</pre>
         <p style="text-align: center;">
          <a href="http://cos.name/?attachment_id=" rel="attachment wp-att-3340">
           <img src="http://cos.name/wp-content/uploads/2011/04/walktrap.community_21.png"/>
          </a>
         </p>
         <p>
          从图中也可以直观地看出，中间度最高的5个节点，确实位于中介的地位。
         </p>
         <p>
          具体看这5个节点：
         </p>
         <pre class="brush: r">V(gg)[bte&gt;=3000]</pre>
         <pre>Vertex sequence:
[1] "邱元杰" "娄谦之" "王子涵" "刘波"   "顾鑫"</pre>
         <p>
          对这5个节点，基本上都有比较合理的解释，其中有三个人是“高中校友”兼“大学校友”，而另外两个则沟通了“网络好友”与“大学好友”。
         </p>
         <h2>
          五、基于好友关系的一种简单的推荐
         </h2>
         <p>
          最后，我们也做了基于好友关系的好友推荐，推荐的逻辑与人人网自身的推荐逻辑相同：根据共同好友的数量来进行推荐。在具体实现的时候，仍然需要考虑用户同名的情况。
         </p>
         <pre class="brush: r">tmp3 = friend_all[!(friend_all[, 4] %in%
        friend_all[friend_all[, 2] == "41021031", 4]), ]
listall = sort(table(tmp3[, 4]), dec = T)
top = names(listall[1:20])
tmp4 = tmp3[tmp3[, 4] %in% top, 3]
top20 = sort(table(tmp4), dec = T)
top20</pre>
         <pre>周科  邹碧筠Phoebe       査小狮       韩晶磊       陆丽娜
55           49           42           41           41
焦丽萍       蔡锡真         高晨       鲁锦彪         张洁
40           39           39           38           38
张明珠       范莉悦       钱咏邠   薛俊波悟空         周迪
38           37           37           37           37
陈素         蒋莹         唐甜         费逸       王丽涵
36           36           36           35           35</pre>
         <p>
          这个推荐的结果与人人网的推荐基本一致（因为逻辑相同嘛），以下是人人网的一些推荐截图：
         </p>
         <p style="text-align: center;">
          <a href="http://cos.name/?p=3324">

          </a>
         </p>
         <p>
          上述推荐的机制较为简单，但是在拥有大量真实关系的网络中，推荐的效率还是比较高的。当然，我们也可以开展对文本与行为的挖掘，以得到超越真实线下关系的推荐，但本文尚未做这方面的尝试。
         </p>
         <p>
          附件2的代码，最新做的图片，统计之都立功啦。

             哦，另外提一点建议：出于隐私保护，建议把上述图片中涉及人名ID的都抹掉！
             <br/>
             国外social network的data都是特别隐私的，用户名ID之类的全部匿名化处理，就算是拿到数据，也是要在受限制的情况下使用，主要考虑大概就是隐私保护吧。虽然人人本身隐私保护不咋地，但是还是建议在这里考虑一下大家的隐私问题，改一下吧，不影响表现效果的。

                 ……既然不是名人，那么叫什么名字，又有什么所谓呢？
                 <br/>
                 既然是名人，他已经先选择了公布自己，比如咱们在网上都是实名的，说明咱们不在乎，那么自然不用匿名化。
                 <br/>
                 我觉得要点是，未经人家同意就曝露人家的信息，那就不好了。总得问过……

               既然网上都搜不到。那么这些名字别人看了能有什么用。如果读者能认识其中的人，说明读者是作者的朋友了，算是作者的圈内人士了。
              </p>
              <p>
               诚如你说“……既然不是名人，那么叫什么名字，又有什么所谓呢？”，那放上去真名也就是无所谓了，但放上真名的一个好处是读者的朋友看了会觉得比较有意思、很好玩，至少有八卦的乐趣。如果是纯粹匿名化，那么和随机生成一个网络贴上去，说说拓扑关系，然后画几张图也就没甚区别了。但这样的文章估计没人乐意看，反正我是不感兴趣的；当然这种随机数据的文章可以来论述理论，但对于像本文一样应用性的文章，如果没有真实数据和真实物理背景，那写还不如不写。
              </p>
              <p>
               至于你说的征求上面名字的意见，我觉得也很值得商榷。首先，对文章出现的名字来说，上面能说明的信息其实不多，除了真实姓名之外，也就几个联系边而已，这个算不得什么隐私吧（至少在国内，国外的标准不考虑）。其次，如果我们每个人写（不涉及到褒贬性的）文章时提到自己朋友时，都去征求一下朋友的意见，看他允许不允许出现自己的真名，那么这个工作量是非常大的，更重要的是这样会很腐朽很荒谬：因为如果连不涉及到褒贬，仅仅陈述客观事实的文章都需要自己朋友来许可的话；那么我们岂不是做什么事情，只要提到朋友的名字都需要事先征求一下朋友的意见？如果真是这样，那么我很怀疑朋友之间的默契和信任。难道姓名真的如此神圣而不可高攀？
              </p>
              <p>
               我觉得保护隐私的注重走得过分远了点，尤其在国外。国内应该适当学习，不应该矫枉过正。
              </p>
              <p>
               我的观点比较非主流，并且比较偏激，见谅，哈哈~

                 其实我真不觉得匿名化会对（社会网络）研究带来阻碍，反而是一种对于被调查者的尊重。名字不过是一个映射、一个代号，关键在于大家想不想在网上被搜到了。
                 <br/>
                 至于隐私有多重要……看看最近iphone闹得沸沸扬扬的地理位置记录事件吧：我自愿公布是我的事儿，你管不着；只是你不应该不告诉我就擅自记录（虽然其实可能我可能不在乎）。
                 <br/>
                 这个没法默认为人家同意吧？尤其是牵扯到“链路预测”，连链路还没形成呢，估计八成是不认识，那么就擅自用人家的信息？当然照片名字之类的或许无什么大碍，更多于我来说是一种“过程”问题吧。

               这个函数我当时写的时候也遇到不少类似的问题，可能还是不够稳健。如果可能的话麻烦你帮忙看一下是在什么情况下出现的这个错误。谢谢~~

             想问下，出现了这样错误信息，数据量太大造成的么？

             ‘memory.limit()’ is Windows-specific

                 版主大人，最近又开始想试试您的那个人人网社交分析的程序，发现用igraph做图，跑以下程序library(igraph) gg = graph.data.frame(d = ff, directed = F) ## png(“net.png”, width = 500, height = 500) par(mar = c(0, 0, 0, 0)) set.seed(14) plot(gg, layout = layout.fruchterman.reingold, vertex.size = 5, vertex.label = NA, edge.color = grey(0.5), edge.arrow.mode = “-“) ## dev.off() 报错，说symbols作的轴错，min(x),max(x)的参数错误，为什么啊

                 版主，经过本任反复看了您的论文，发现出现我上述的问题，是对N=0,N=1,N=2分别提取了数据（果然等了半天），直接串联成了矩阵……我再试试看，看看能否再现您的方法

                 系统应该是可以的  因为我同学成功过
                 <br/>
                 然后他用的是FIREFOX的 但是我用的是CHROME
                 <br/>
                 我在想是不是浏览器的问题
                </p>

             最新的RCurl可以连到新浪微博，但是用类似的代码却没办法连到人人，不清楚具体是什么原因。希望对此有研究的同学给点参考。人人网的登录过程算是比较简单的，新浪微博的好复杂。

             2011-06-20 增加了新的代码，可以直接获取“共同好友”。如果只需要分析好友的群组关系（而忽略好友推荐功能），可以直接运行这段代码，大幅度提高效率，几分钟就能搞定，同时绕过好友同名的问题。欢迎试用，如需修改参数麻烦自行操作。=”=

             相关的RCurl版本为1.5-0.1，1.6的版本仍然没有搞清楚，仍然请教各位。

               咦，这里貌似没有这样的代码呀。原来的代码里面是u0=strsplit(hh[grep(“的好友“,hh)],”的好友“)[[1]][1]，用来取个名字的。我刚才跑了一遍，没发现这样的错误。
               <br/>
               话说，这种代码的一个问题是如果目标网站的脚本变了，我的代码就跑不动了，这个应该怎么处理呢？

             版主你好，看了你的大作，实在佩服。而且你细心地回答大家的问题，就更加的佩服了。我也是来打扰你一下的。因为你给的代码里面注释比较少，有些地方不知道该怎么做。我现在已经将我的好友的列表抽取出来了，但是没能抽取到我的好友的好友，哪一个地方要修改一下？我用的是你最新的那个代码的。另外，我是刚初学R的，你说把数据集保存到net.1去，该怎么操作？

               好友的好友，需要用第一个代码附件。就是类似net.1=f.renren.friend(uid0=”****”,name=”****”,pwd=”******”,N=0)这样的。这个耗时比较长的，因为是一个一个地抓取，不知道有什么方便的做法没。

             现在发现了另外的一个问题。我总共有133个人人好友，按照你的代码运行之后能抽出133个好友。但是奇怪的是，在列出133个好友之后，会单独的列出两个好友的名字
             <br/>
             [1] “132”                      “蔡鸿培”                   “1”                        “Tue Oct 11 18:50:29 2011”
             <br/>
             [1] “133”                      “周郁霖”                   “1”                        “Tue Oct 11 18:50:29 2011”
             <br/>
             [1] “宋元璟” “赖智辉”
             <br/>
             就是这个样子。然后我执行命令 justfriend的时候，列出的一下subgroup，这两个同学是我们班上比较活跃的，一个还是班长，都加了大家人人的，可是他们两个却均独立为一个subgroup，这是为什么呢？

               最后列出两个名字，是中间度位于前1%的人的名字。至于为什么这两个人会被算法做成独立的子群，这个就得看具体算法啦，你可以调整参数试试看，数据的话就是最后结果里面的friend

                 非常感谢版主那么及时的回复！暂时遇到了比较多的问题。我运行第二个附件的代码，数据是抽取出来了，图像也画出来了。但是我输入friend，显示的结果四个都是0，只有一行。不知道哪里出错了。
                 <br/>
                 而运行第一个附件的代码，运行过程没有出错，但是没有打印出任何的信息，不知道是哪里的问题。
                 <br/>
                 我想如果运行第二个附件的代码，要将数据集赋给net.1应该是
                 <br/>
                 net.1&lt;-friend 只是我这里的friend出问题了。打扰你了，可能还要再打扰你

             刚才提出问题我们又进行了验证，只要不超过100个好友，程序没问题。经分析跟物理机的内存大小有关，32位的机器只能是4G，所以造成数据溢出？？？？

                 如果我的文件是UTF-8编码的是不是需要更改源码，我看到里头有用iconv，但去掉还是登录不上，返回用户名或密码错误页面。

                 如果直接用您的源文件直接不允许有多字节字符……

             当时人人网并不是单纯按照共同好友数量来推荐。设想一个场景，如果你进了一个新公司，而公司的同事大部分是玩人人网的。假设你所在部门的不少人都把你加成了好友，这样很多你不认识的同事跟你的共同好友很容易就变得很多，这样你的推荐位就被这些人占着，这样的结果显然是用户不想得到的。人人网当时就采用其他的方法解决了这个问题。

             plot中的“vertex.color = V(gg)$color”是赘述，com$membership + 1的作用是避免彩虹色带的大红色，rainbow(max(V(gg)$sg))[V(gg)$sg]要改为：rainbow(max(V(gg)$sg + 1))[V(gg)$sg]。。。。窃以为。。。
